Happy Thursday, everyone! Let's flutter onto our next post in our New Mexico’s Iconic Bugs Special! 🦋
New Mexico is home to more than 300 butterfly species, but only one was officially designated the state butterfly in 2003—the Sandia Hairstreak (Callophrys mcfarlandi).
First discovered in New Mexico, this is the Sandia Hairstreak’s primary habitat, though it can also be found in other regions throughout the United States. It has a wingspan of about 1.1 -1.25 inches and is easily identified by its golden-green underside, marked with a thin white line bordered in black. The upper wings are brown in males and reddish-brown in females, with a narrow black border.
Sandia Hairstreak larvae feed only on the flowers and developing seeds of beargrass (Nolina spp.), a grass-like plant common in New Mexico and closely related to agaves and yuccas. Caterpillars range in color from pink to maroon to green before pupating. Adults typically emerge and fly from early spring to early summer, often living for about one to two weeks. During this brief time, they focus on mating and laying eggs. This species is found on dry, rocky hillsides, slopes, open woodlands, and grasslands where beargrass grows. Adults are most active in the morning and settle near the base of plants at night. 🌙
